Firmware updated EX8000 keeps dropping Internet

Hi Kicoman et al, 

So other than supplying various logs there has been no resolution. Indeed the suport team are located in Malaysia.  That said I had other issues such as the extender which had 4 ethernet cables connected from it to three laptops and a Hive power hub and believe it or not at times it would randomly drop the wired connection to one or more devices whilst other were still connected, how does that work? - I cannot win. Anyway round file - done.
